This well designed 25W per channel stereo power amplifier can be used to boost the output of an existing lower power car stereo system. The input should be in the region of 1 to 5 Watts with 2W output being the ideal level.

It can be connected directly to the output of the car stereo (cassette player, CD player or radio). It employs two TDA1515 ICs. Two heatsinks provided.
